Lab Girl: A Story Of Trees, Science And Love
by Hope JahrenLab Girl is a book about work and about love, and the mountains that can be moved when those two things come together. It is told through Jahren's remarkable stories: about the discoveries she has made in her lab, as well as her struggle to get there; about her childhood playing in her father's laboratory; about how lab work became a sanctuary for both her heart and her hands; about Bill, the brilliant, wounded man who became her loyal colleague and best friend; about their field trips - sometimes authorised, sometimes very much not - that took them from the Midwest across the USA, to Norway and to Ireland, from the pale skies of North Pole to tropical Hawaii; and about her constant striving to do and be her best, and her unswerving dedication to her life's work.Visceral, intimate, gloriously candid and sometimes extremely funny, Jahren's descriptions of her work, her intense relationship with the plants, seeds and soil she studies, and her insights on nature enliven every page of this thrilling book. In Lab Girl, we see anew the complicated power of the natural world, and the power that can come from facing with bravery and conviction the challenge of discovering who you are.

A Lab of One's Own: One Woman's Personal Journey Through Sexism in Science
by Rita Colwell Sharon Bertsch McGrayneA riveting memoir-manifesto from the first female director of the National Science Foundation about the entrenched sexism in science, the elaborate detours women have taken to bypass the problem, and how to fix the system. If you think sexism thrives only on Wall Street or in Hollywood, you haven&’t visited a lab, a science department, a research foundation, or a biotech firm. Rita Colwell is one of the top scientists in America: the groundbreaking microbiologist who discovered how cholera survives between epidemics and the former head of the National Science Foundation. But when she first applied for a graduate fellowship in bacteriology, she was told, &“We don&’t waste fellowships on women.&” A lack of support from some male superiors would lead her to change her area of study six times before completing her PhD. A Lab of One&’s Own documents all Colwell has seen and heard over her six decades in science, from sexual harassment in the lab to obscure systems blocking women from leading professional organizations or publishing their work. Along the way, she encounters other women pushing back against the status quo, including a group at MIT who revolt when they discover their labs are a fraction of the size of their male colleagues&’. Resistance gave female scientists special gifts: forced to change specialties so many times, they came to see things in a more interdisciplinary way, which turned out to be key to making new discoveries in the twentieth and twenty-first centuries. Colwell would also witness the advances that could be made when men and women worked together—often under her direction, such as when she headed a team that helped to uncover the source of the anthrax used in the 2001 letter attacks. A Lab of One&’s Own shares the sheer joy a scientist feels when moving toward a breakthrough, and the thrill of uncovering a whole new generation of female pioneers. But it is also the science book for the #MeToo era, offering an astute diagnosis of how to fix the problem of sexism in science—and a celebration of the women pushing back.

Label-Free Super-Resolution Microscopy (Biological and Medical Physics, Biomedical Engineering)
by Vasily AstratovThis book presents the advances in super-resolution microscopy in physics and biomedical optics for nanoscale imaging. In the last decade, super-resolved fluorescence imaging has opened new horizons in improving the resolution of optical microscopes far beyond the classical diffraction limit, leading to the Nobel Prize in Chemistry in 2014. This book represents the first comprehensive review of a different type of super-resolved microscopy, which does not rely on using fluorescent markers. Such label-free super-resolution microscopy enables potentially even broader applications in life sciences and nanoscale imaging, but is much more challenging and it is based on different physical concepts and approaches. A unique feature of this book is that it combines insights into mechanisms of label-free super-resolution with a vast range of applications from fast imaging of living cells to inorganic nanostructures. This book can be used by researchers in biological and medical physics. Due to its logically organizational structure, it can be also used as a teaching tool in graduate and upper-division undergraduate-level courses devoted to super-resolved microscopy, nanoscale imaging, microscopy instrumentation, and biomedical imaging.
Labnet: Toward A Community of Practice (Technology and Education Series)
by Richard Ruopp Shahaf Gal Brian Drayton Meghan PfisterConnected by a computer telecommunications network, ninth-graders from eight high schools scattered thousands of miles across Alaska work together, building a robot submarine to gather samples from the floor of Prince William Sound. This is high school science as some teachers and educational reformers today envision it -- centered on student projects that encourage learning by doing...supported by modern technology...enriched by collaboration among students and teachers, both face to face and far apart. This example is drawn from LabNet, a three-year effort funded by the National Science Foundation. The project was conducted by Technical Education Research Centers (TERC), a nonprofit educational organization dedicated to improving mathematics and science education. Eventually reaching 562 teachers in 37 states, Puerto Rico, and American Samoa, LabNet had a direct impact on their classroom practice. In a follow-up evaluation, the majority said they had assigned their students more projects and had used LabNet's telecommunications network to exchange project ideas with other teachers. This book is the story of LabNet as told by its editors, with 14 additional essays on science projects -- both theoretical and practical -- by LabNet teachers and TERC staff.

Labor and the Locavore
by Margaret GrayIn the blizzard of attention around the virtues of local food production, food writers and activists place environmental protection, animal welfare, and saving small farms at the forefront of their attention. Yet amid this turn to wholesome and responsible food choices, the lives and working conditions of farmworkers are often an afterthought.Labor and the Locavore focuses on one of the most vibrant local food economies in the country, the Hudson Valley that supplies New York restaurants and farmers markets. Based on more than a decade's in-depth interviews with workers, farmers, and others, Gray's examination clearly shows how the currency of agrarian values serves to mask the labor concerns of an already hidden workforce. She also explores the historical roots of farmworkers' predicaments and examines the ethnic shift from Black to Latino workers. With an analysis that can be applied to local food concerns around the country, this book challenges the reader to consider how the mentality of the alternative food movements implies a comprehensive food ethic that addresses workers' concerns.
Labor in the Era of Globalization
by Clair Brown Barry Eichengreen Michael ReichThe third quarter of the twentieth century was a golden age for labor in the advanced industrial countries, characterized by rising incomes, relatively egalitarian wage structures, and reasonable levels of job security. The subsequent quarter-century has seen less positive performance along a number of these dimensions. This period has instead been marked by rapid globalization of economic activity that has brought increased insecurity to workers. The contributors to this volume, prominent scholars from the United States, Europe, and Japan, distinguish four explanations for this historic shift. These include 1) rapid development of new technologies; 2) global competition for both business and labor; 3) deregulation of industry with more reliance on markets; and 4) increased immigration of workers, especially unskilled workers, from developing countries. In addition to analyzing the causes of these trends, the contributors also investigate important consequences, ranging from changes in collective bargaining and employment relations to family formation decisions and incarceration policy.
Laboratory Accreditation and Data Certification: A System for Success
by Carla H. Dempsey Jimmie D. PettyThis book provides descriptions of current laboratory accreditation schemes and explains why these schemes fall short of assuring data purchasers that the data produced from accredited laboratories are always quality products. The book then presents a system for laboratory accreditation in conjunction with data certification that assures data purchasers their data are useful for the purposes for which they are intended. Simple quality assurance and quality control techniques, in addition to concepts of total quality management, are described and then applied to the environmental laboratory industry. This "System For Success" was developed from real problems and real solutions within the industry and represents an integration of proven techniques that offer a better way to ensure quality laboratory data is obtained. Laboratory Accreditation: A Workable Solution is a must for government officials, environmental professionals, independent environmental laboratories, hazardous waste disposal industries, chemical manufacturers, QA professionals, and testing laboratories.

Laboratory Design, Construction, and Renovation: Participants, Process, and Product
by Committee on Design Construction Renovation of Laboratory FacilitiesLaboratory facilities are complex, technically sophisticated, and mechanically intensive structures that are expensive to build and to maintain. Hundreds of decisions must be made before and during new construction or renovation that will determine how successfully the facility will function when completed and how successfully it can be maintained once put into service. This book provides guidance on effective approaches for building laboratory facilities in the chemical and biochemical sciences. It contains both basic and laboratory-specific information addressed to the user community-the scientists and administrators who contract with design and construction experts. The book will also be important to the design and construction communities-the architects, laboratory designers, and engineers who will design the facility and the construction personnel who will build it-to help them communicate with the scientific community for whom they build laboratory facilities.
Laboratory Exercises for Sensory Evaluation
by Harry T. LawlessLaboratory exercises are a necessary part of science education. They enable students to better understand the principles discussed in lectures, and provide them with hands-on experience of the practical aspects of scientific research. The purpose of this book is to provide students and instructors with a time-tested set of lab exercises that illustrate the common sensory tests and/or sensory principles used in evaluation of foods, beverages and consumer products. The appendices will also include a set of simple problem sets that can be used to teach and reinforce basic statistical tests. Approximately twenty years ago the Sensory Evaluation Division of the Institute of Food Technologists sponsored the preparation of a set of exercises titled "Guidelines for Laboratory Exercises for a Course in Sensory Evaluation of Foods," edited by one of the co-authors (Heymann). This book will provide additional materials from the second author (Lawless), as well as other instructors, in a uniform format that can be easily adopted for course use. Most importantly, the lab exercises will complement the flagship textbook in the field, Sensory Evaluation of Foods: Principles and Practices, 2E, also by Lawless and Heymann and published by Springer. Possible course adoption of the main text along with the lab manual should enhance the sales of these materials.
